SPRING LOADED DEVICES

Vlier

Vlier's Stubby®
spring loaded devices offer the advantages of a ball plunger's short body
with the long nose of a spring loaded device. These compact units provide
considerable plunger travel and high end forces in applications where
space is restricted-their bodies are only half the length of spring loaded
devices, yet plunger travel is twice that of a ball plunger.Case hardened nose-Offers excellent wear resistance; however, core
is ductile to reduce possibility of fracturing under impact. Steel Version
only.Available with steel, stainless steel or Delrin noses.

Nose telescopes completely-Permits use where mating surfaces must
be flush.Quickly installs from either end-Only tool required is a Vlier
Wrench.
